Erwin Koeman has resigned as coach of FC Utrecht after failing to resolve a series of disagreements with the club's board.

Koeman only took over this summer but quickly became frustrated after Utrecht sold key players Dries Mertens, Kevin Strootman, Michel Vorm, Ricky van Wolfswinkel and Michael Silberbauer.

Talks aimed at ending the dispute failed to find a resolution, leading to Koeman's departure with Jan Wouters swiftly named as his replacement.

A statement on the club's official website read: "The collaboration between FC Utrecht and Erwin Koeman has ended.
At the request of the coach his contract has been terminated with immediate effect.

"Koeman has taken this decision as he believes the working conditions do not meet his requirements. There have been various discussions between the club's management and Koeman but the coach did not see the desired progress in the short term.

"FC Utrecht do not feel they can meet Koeman's conditions and have agreed to his request to have his contract rescinded.''

Wouters, one of Koeman's assistants, will be in charge for this weekend's home clash with Heerenveen. Robby Alflen will be his number two. Utrecht are 10th in the Eredivisie having won just one of their last four league games.
